\ n This invention relates to frames for ings in or through walls.

l This invention has utility when incorporated in protective structures, more especial- 5 ly as metallic door frames for assembly in vault walls, being readily conformable to different Wall thicknesses for snug anchoring in position at the place of installation, thereby avoiding `tactory dimensioningas to door- Way distance through the wall.

Referring to the drawing: f Fig; 1 is a` Jfront view of a vault doorway having an embodiment `of the invention inycorporated therein; t

Fig. 2 is a section on theline I1-II,F1g. 1 Fig. 9 is a section on the line `III--g-III,

opent) Fig. 1; and v Fig. 4 is a section onthe line IV-IV,

Fig. 1. y.

There is shown structure having wall 1 with outer face 2 and inner face 3 about open- `ing 4, herein shown to provide a doorway in a protective structure, say a vault.

Outer Wall abutting flange 5 has therefrom 5 l and inwardly extending into the opening 1,

" throat flange 6. These flanges 5, 6, form an outer angle metal door frame. Inner wall abutting flange 7 with throat flange 8 form an oppositely disposed inner angle metal` o tdoor frame. Fixed on the inner face of the flange 5 is a series of nuts 9. In alignment therewith, the flange 7 has openings 10 therethrough for nuts 11 having notches or seats 12 for engagement by a screw driver. These` 5 nuts`11 are thus rotatable as to the flange 7 inengagement `with threaded portion 13 of studbolts 14 havingl their threadedpor- Y tions 14 engaged in the nuts 9.

The vault wall 1 of masonry, masonry 0 and metallic sheathing, reinforcement, and other protective construction material, Vmay have a wide range of thicknesses. Fora given dimension opening, the frames 5, 6, and i `7, 8, are readily utilized notwithstanding 5 ranges of wall thiclmess.

To bridge the spacing in the throat o `the -doorway between the free ends of the fianges 6, 8, there is provided plate or sheet metalthroat extension 15 engaging in seats 50116 anchored at points along the side of the therethrough i i ,4 y i v Trim21 `1 may be :assembled with the door frame proper `by spot welds 22. Bars "23 de- 70 termineclearance for this trim 21` which is providedwith hinges 24:` mounting `the vault `door 25 having tumbler combination lock 26 operable to release spindle127, soi that bolts 28 may be thrown to permitopeningof .the` 75 .door 25. The bolts .28 `in locking `position thewall `thus a clear" doorwaym :The extension 15 engaging in these seatswlyprotrudes past theange to have telescopingvcoactiony with the flange 8 on the sidethereof ftowardithe wall 1. The plate 55 or;exte"nsion15 `is yieldably held insnug seat- --ingirelation with the flange 8 by springguides 'y j17between-which guidesfand the flangeS the extensionimaywride asthe nuts 11 are operated tto drafwwtheiangle frames toward )each other in:clampingsuch` frame as a unit in the opening. F orthe .doorway threshold,

blocks 18 may have the space therebetween `bridged by rplate 19 having stiifening angle 20 .anchored therebelow. `There .is thus proy Avided a smooth continuous tread intoand out tof `the @vault for `ready `wheeling of loads pass through openings29 intol pockets 30 on theangle flange 6 of the "outerdoor frame. The door and frame with outwardly extending flanges may beset in a Wall opening with @0 Y i the outer llange abutting the outer face of the wall and the inner frame set on the inside of the "wall with a flange thereofabutting the inside wall.` Stay' bolts connect the frames to hold them firmly in aligned posi-85 tion and clamp the filler plates therebetween. As so held, mortar or grouting may be used to effect more firm assembly. The door may then be assembled, even by omission ofthe 96 trim 21, if such be desired. ..1

What is claimed and it is desired to secure by Letters Patent is:

1. In-a wall having an opening, a frame therefor comprising a pair of members, one

about the opening on each side of the wa11,-`

said members each having a wall-engaging flange and a throat-forming flange extending therefrom into the opening, said throat-forming flanges extending toward each otherand providing a space therebetween, a space- `100 bridging member about the throat-forming flanges, means positioning said space-bridging member comprising a member on one of said flanges definitely positioning said spacebridging member as to one of the frame members, ieXible means coacting with aviange on the opposing frame member to grip thespaoebridging member therebetween to resist shiting thereof beyond assembled position, and means extending .pastthe spaoe-.brdgingmember between the members aboutthe opening for drawing said members into assembled position thereby to clamp the space-bridging member between the frame members.

2. In a wall having an opening, a frame therefor Acomprising :a pair .of members, one about the opening on each side of the W-all, said members each having .a Wall-engaging "iange and a .throat-forming Hangeextending therefrom into the opening, said throat-form# ing flanges extending toward each other .and providing a space therebetween, .av spacebridging member about the throat-forming flanges, means positioning sai-d space-bridging member as Ato the frame members comprising a clip on oneof said members forming a seat against ywhich the space-bridgingmem ber ooacts Ator Ydelinitely spacing such member as to the frame member, a spring inger carried by the Aother frame member mounted -to grip toward the throat-forming flange thereof, between which iinger and'iiange the space-bridging member extends to be held therebetween against normal shiiiing, .and means for draw-ing the frame members jtoward each other for frame assembly, said v space-.bridging member being thereby shift- -a-ole .into assembled position between ythe iinger and the ange toward which the inger has gripping action.

In witness whereof We aiiix .oilr signatures.
